    Research on Heterogeneous Spatial Distribution of Topsoil Moisture in Typical Naturally-regenerated Montane Broad-leaved Mixed Forests of Northern China

    By geostatistic,the heterogeneous spatial distribution of topsoil moisture in typical naturally-regenerated montane broad-leaved mixed forests of Northern China were analyzed quantitatively.The results showed that in Betula platyphylla-Populus davidiana dominated broad-leaved forests,the topsoil moisture did not differ greatly among different quadrats.The heterogeneous spatial distribution of topsoil moisture was obvious in a small range(13.10 m),the spatial auto-correlated factors accounted for a large proportion(71.9%).A great spatial pattern was observed.
